YARN-SPINNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 741,101, dated October 13, 1903.

Application filed January 14,1903. serial No- 138,951. (No model.)

To all whom it may concern.-

Be it-known that I, JOHN BOOTH, of Gentral Falls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in YarmSpinning Apparatus, of which the following is a specification. I

This invention relates to that class of spinning apparatus in which a spinning-ring is automatically adj nstable relatively to its support, the ring having a limited free movement vertically and horizontally or edgewise and being prevented from rotating, as sho'wnin Letters Patent of the United States No. 705,733, granted to me July 29,1902.

The invention has for its object to provide improved means for so connecting a spinningring with a supporting-base adapted to be rigidly attached to a ring-rail as to permit the automatic adjustment of the ring to the axis of the spindle, while preventing the ring from rotating.

The invention also has for its object to permit the reversal of a ring provided with two races, so that when one of the races has been worn by the traveler the ring can be reversed or inverted and the other race brought into position for use.

Theinvention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a top plan view of a spinning-ring and its supporting-base embodying my invention. Fig. 2 represents an edge view of the ring and its supporting-base. Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 4 represents a view similar to Fig. 3, showing the ring raised from the base and moved sidewise from the position shown in Fig. 3. Fig. 5 represents a perspective View of one of the clips secured to the ring.

The same reference characters indicate the same parts in all the figures.

In the drawings, a represents a ring, which is preferably a reversible ring of the Draper or Carroll type and has at each edge an outwardly and an inwardly projecting flange, collectively constituting a traveler-race ct, there being therefore two traveler-races, one at the upper and the other at the lower edge of the ring.

12 represents the supporting-base, which is adapted to be affixed rigidly to a ring-rail and may be of any suitable form. As here shown, the base is provided with a flange 2), adapted to bear on the top surface of the ringrail, the portion of the base below the flange being formed to fit snugly in an orifice in the rail. The lower edge portion of the ring rests loosely upon the base and is movable to a limited extent vertically toward and from the base and horizontally parallel with the 1 plane of the base, the ring and base being provided with means, as hereinafter described, for permitting the above -described movemen ts of the ring and at the same time preventing its rotation, said means being as follows: The base 17 is provided with a series of orifices 19 preferably three in number and arranged at equal distances apart. Said oriiices cooperate with projections or clips of, detachably secured to the lower portion of the ring, in preventing the rotation of the ring. The clips a are in this case detachably secured to the lower race ct, and, as here shown, are composed of strips of wire, pref erably flat or oblong in cross-section, bent at their ends to form opposed ears or jaws 2 2, adapted to detachably grasp the flanges forming the said lower race. The body portions'of the clips are formed into loops projecting below the ring, each loop having two vertical side portions 3 3 and a horizontal central portion 4, the latter passing through one of the orifices b ficient size to permit the clips to move in them to a limited extent both horizontally and vertically, thus permitting limited horizontal and vertical movements of the ring without permitting the ring to rotate. The jaws 2 2 of the clips are pressed inwardly by the resilience of the clips with sufficient force to hold the clips in frictional engagement with the lower portion of the ring and cause the clips to prevent free rotation of the ring on the base. The ring may be rotated, however, by applying to it suflicient force to overcome the frictional hold of the jaws of the clips on the ring. Hence the ring may be turned or partially rotated from time to time to compen- Said orifices are of sufsate for unequal wear of the ring-traveler on the race with which it is engaged.

It will be seen that the detachability of the clips a from the ring enables said clips, after the upper race a has been rendered useless by wear as a guide for the ring-traveler, to be inverted, so that the race which before was at the lower edge of the ring will be at the top, the worn race resting on the base and being equipped with the clips a It will also be seen that the described improvements enable an ordinary reversible ring to be supported so that it will be automatically adjustable to the axis of the spindle without being permitted to rotate, no change or adaptation of the ring being required. I do not limit myself, however, to a reversible ring, as the clips may be applied to the lower portion of a ring of any suitable form adapted to engage the jaws of said clips.

I claim-- 1. A ring-supporting base adapted for at tachment to a ring-rail, and a ring having projections or clips provided with opposed jaws detachably grasping its lower edge portion, said base and clips having provisions for permitting limited movements of the ring, substantially as set forth.

2. A ring-supporting base adapted for attachment to a ring-rail, and a reversible ring having projections or clips detachably secured to one of its traveler-races, said base and clips having provisions for permitting limited movements of the ring, substantially as set forth.

3. A ring-supporting base adapted for atvtachment to a ring-rail, and a ring having downwardly -extending projections or clips provided with opposed jaws detachably grasping its lowerportion, said base having orifices formed to cooperate with the lower portions of said clips in permitting free limited edgewise and vertical movements of the ring and in preventing its rotation.

4. A ring-supporting base adapted for attachment to a ring-rail and provided with orifices, and a ring having downwardly-projecting clips frictionally engaged with its lower portion and passing through said orifices, the frictional engagement of the clips with the ring permitting the ring to be adjusted to compensate for wear of its traveler-race.

5. A ring-supporting base adapted for attachment to a ring-rail and provided with orifices, and a ring having downwardly-projecting clips frictionally engaged with its lower portion and passing through said orifices, said clips having ears or jaws at their end portions and loops depending from said ears and passing through the orifices.

In testimony whereof I have affixed my signature in presence of two witnesses.

JOHN BOOTH.
